What is PointNet in Deep Learning?
PointNet analyzes point clouds by directly consuming the raw data without voxelization or other preprocessing steps. A Stanford University researcher proposed this novel architecture in 2016 for classifying and segmenting 3D representations of images. Key Properties PointNet considers several key properties when working with point sets in 3D space. Permutation Invariance A point cloud consists of unstructured sets of points, and it is possible to have multiple permutations within a single point cloud. If we have N points, there are N! ways to order them. Using permutation invariance, PointNet ensures that the analysis remains independent of ...

Read MoreSkin Cancer Detection using TensorFlow in Python
Early detection of any disease, especially cancer, is very crucial for the treatment phase. One such effort made in this direction is the use of machine learning algorithms to detect and diagnose skin cancer with the help of a machine learning framework like TensorFlow. The traditional method of cancer detection is quite time-consuming and requires professional dermatologists. However, with the help of TensorFlow, not only can this process be made fast, but more accurate and efficient. Moreover, people who do not get timely access to doctors and dermatologists, can use this meanwhile. Algorithm Overview The skin cancer ...

Read MoreHow to encode multiple strings that have the same length using Tensorflow and Python?
Multiple strings of same length can be encoded using tf.Tensor as an input value. When encoding multiple strings of varying lengths, a tf.RaggedTensor should be used as an input. If a tensor contains multiple strings in padded/sparse format, it needs to be converted to a tf.RaggedTensor before calling unicode_encode. Read More: What is TensorFlow and how Keras work with TensorFlow to create Neural Networks? Let us understand how to represent Unicode strings using Python, and manipulate those using Unicode equivalents. We separate the Unicode strings into tokens based on script detection with the help of the Unicode equivalents ...
Read MoreHow can Tensorflow be used to create a pair using a file path for the flower dataset?
TensorFlow can process image datasets by creating (image, label) pairs from file paths. The flowers dataset contains thousands of flower images organized in subdirectories, where each subdirectory represents a different flower class. Read More: What is TensorFlow and how Keras work with TensorFlow to create Neural Networks? We are using Google Colaboratory to run the below code.
